davmail not starting

So, attempting to install davmail on pretty much a new install - ran the deb, tried to run it, didn't open but appeared to be running. Did have java installed (only have openjdk installed, unlike my other install where sunjava causes the problems with davmail), and when I ran it from the command line I get:

Exception in thread "SWT" java.lang.UnsatisfiedLinkError: Could not load SWT library.

Which led me to this bug report (under DavMail, even though it's a openjdk bug?), which solved it with:

sudo apt-get install libswt-cairo-gtk-3-jni

which worked a treat.
